I'm not sure what the best way to fix this is.  These functions are 
defined in c-common.c.  Lemme guess, fortran doesn't use c-common.o :).

cw-asm support was hacked into the apple compiler in a pretty ugly way. 
If possible, one solution might be to link c-common.o into gfortran: I'm 
not sure if it would work.  If that doesn't work, we can move the cw-asm 
support stuff from c-common.c to some other .c file that is generally 
available.  Alternatively, we could #ifdef out the referneces if not 
compiling the C compiler.

I'm not sure what the best approach is.
